undoubtedly essential to the development of Delta plans generally. But science is only a starting point in the development of an integrated watershed-based plan, and it must be broadly applied. Moreover, science by itself cannot generate solutions to the myriad problems of the Delta that will satisfy the interests of all parties. Water scarcity in California is very real and science is not necessarily the sole solution to California’s water problems. There is simply not enough water to serve all desired uses. The situation surrounding the Delta is a symptom of scarcity. The effective management of scarcity requires not only the best science and technology, but also consideration of public and private values, usually through political processes, to arrive at plans of action which are scientifically sound but also incorporate and reflect the mix of differing societal values.
This review contains a background section describing the geography, hydrology, and history of the Delta and more detailed explications of the points noted above. Then the discussion is organized according to: (1) critical gaps in the scope of the draft BDCP, (2) the use of science in the draft BDCP (3) adaptive management in the BDCP, and, (4) the fragmentation of management that appears to characterize the effort.
